You can try to use custom classloader to load/unload specific classes on demand. But it's a tricky issue - you have to be sure, that there's no instance of a class being unloaded.I wasn't aware of SessionManager. However, I'm not sure it will help. Generally we are installing patches on a live server that has transactions/activity going on while we patch. I'd like to know if its possible for us to do a hot patch without causing any disruption to any user. If we reload, it will cause users to lose data that they are working on.
Maybe some kind of cluster would help - you shutdown one node, update it, bring it back, do the same with the second node, and users - in theory - don't see any problem.
